So, how many bugs will Band of Misfits have? I think Doug had an obscure one he never fixed.
Some weird interactions with existing cards:
- Scheme needs to choose an Action card you have in play. But if you played, say, both a Village, a Band-of-Misfits-as-a-Village, and a Band-of-Misfits-as-a-Smithy, the interface for this becomes tricky to get right.
- Crossroads looks at "have I played Crossroads previously on this turn". I figure BoM-as-XR should count. Tricky to code though.
- Throne Rooming or King's Courting a BoM: after the first choice of card, it becomes that card, so you don't get to change it the second/third plays.
- Play a BoM as a Treasure Map with another Treasure Map in hand. You trash it and the Treasure Map from your hand. Do you get 4 Golds? TMap says "if you do trash two Treasure Maps". Note that, going by BoM wording, it does not become a Treasure Map until after being played. So I think at the time you trash it, it's not a Treasure Map, and therefore you don't get 4 Golds.
Furthermore, since the card actually leaves play while being played, BEFORE "this is that card until it leaves play" takes effect, it actually becomes a Treasure Map permanently once in the trash. If you Graverobber it from the trash, you can then later play it as a normal Treasure Map to trash it, and at that point it becomes a BoM again in the trash. LOL? - Play a BoM as an Island. As with TMap, it leaves play before the "this is that card until it leaves play" instruction, so it actually is still an Island on the Island mat, and therefore counts for 2 VP at the end of the game.
Well, Donald X. would have to step in, but in my opinion, leaving play means getting trashed or being placed on a mat, so BoM becomes BoM in those instances. Also, I would say it is very clear that you can play BoM as a TM, but you would need an actual TM in your hand to trigger the effect.
Well here is why I think this way. The Band of Misfits wording is: "Play this as if it were an Action card in
the supply costing less than it that you choose. This is that card until it leaves play." Two steps. In Dominion, when there are two steps, you always do them in order.
So okay, let's play a Band of Misfits. First step: "play this as if it were an Action card in the supply costing less than it that you choose". OK, TMap is in the supply, and I choose it, and now play as it. First step: "trash this and another copy of Treasure Map from your hand". Okay, I trash the Band-of-Misfits (which is still a BoM, keep in mind!), at which point it leaves play, along with a Treasure Map from my hand. Next step: "if you do trash two Treasure Maps, ...". But I didn't, I trashed a BoM and a TMap, so I don't get the reward.
Okay, done first step of BoM. Second step: "this is that card until it leaves play". That is, the BoM (which is now in the trash) becomes a Treasure Map, "until it leaves play". Well, it already left play, so too late, it'll need to leave play again sometime later to revert back to BoM.
